According to an embodiment of the present invention, a fuel cell stack including: a membrane electrode assembly including an electrolyte membrane, an anode, and a cathode; and separation plates which are arranged on both sides of the membrane electrode assembly and include a cooling water flow channel, an air flow channel, and a fuel flow channel formed thereon. On an end portion of the separation plate, a cooling water outlet manifold, which communicates with the cooling water flow channel, and an air inlet manifold, which is formed to be close to the cooling water outlet manifold and communicates with the air flow channel, are formed. At least one cooling pin for transferring heat is formed on the cooling water outlet manifold and the air inlet manifold. According to an embodiment of the present invention, the fuel cell stack has the cooling pins on the air inlet manifold and the cooling water outlet manifold and thus provides an effect of efficiently transferring heat between the air input manifold and the cooling water outlet. |
